12 Claims.

My invention relatesto vulcanizer adapters, and more particularly to adjustable adapters for automobilev tire .vulcanizers, to adapt same to tires of different sizes.

IFor matter shown but not claimed hereinp referenceis made to my co-pending applications: Serial No. 10,600, filed March 12, 1935, and Serial No: 14,427, filed April 3, 1935.

Important objects of the invention are to pro tires of different sizes, and to provide shoulder plates in -such an adapter that are adjustable to difierent diameters but at all times presenting a complete circle to tires to be vulcanized.

Another object is to provide adjusting means for such adapters.

Still other objects reside in novel ways of mounting shoulder plates upon tread plates comprised in the invention.

The invention also comprises novel details ofconstruction and novel combinations and arrangements of parts, which will more fully appear in the course of the following-description. In the drawings, like reference characters des ignate similar parts in the'several views:

Fig.1 1 is a sideview'of an adapter embodying features of the presentinvention.

Fig. 2 is anenlargedsection, taken on the line 2-2 of Fig. 1.

Fig. 3 is ausimilarly enlarged section, taken on the line 3-3 of Fig.1.

4 is a broken elevation, looking in the direction of the arrows- 4-4 of Fig. 3.

Fig. 5=is a. section'taken on the line 55 of 'Fig. 3.

Fig. 6 is a side elevation of a modified construction.

Fig. 7 is an enlarged section taken on the line 1-! of Fig. 6. v Fig. 8 is a section taken on the li'ne 88 of Fig.7.

Figures 9 and 10 are broken, sectional views illustrating further modifications;

Refern'ngmore in detail to the drawings, the reference number 12 designates a sectional tread plate, It is to be understood that the inner, tire-engagingface I3 of the tread plate may have anydesired design engraved therein for reproduction on the tire. A lateral groove M suggests such engraving. A shoulder plate I5, slidable on the tread plate, has a'boss it that fits in the groove Hand closes the outer end ,thereof and is slidable longitudinally of the groove This boss prevents rubber from fiow-- 32 has a steam space 34.

ing from the tire and escaping under the shoul- I der plate, thru the groove.

The shoulderplate l5 comprises end-abutting sections ll provided with flanges l8 that also abut at their ends. Lugs l9, which project from these flanges, have elongated slots 20 forreceiving bolts 2| that are screwed into tapped openings 22 in the tread plate. Crank handles 23 are provided for manipulating these bolts- Helical springs 24 urge the shoulder plate sections outward with respect to the tread plate l2.

The faces of the shoulder plate and the tread plate that engage during the sliding of the one on the other are preferably inclined from the horizontal, as shown in Figures 2, 3, and '7. For tires of greater thickness, the shoulder plate is moved from the full line positionto the broken line position in Fig. 2. Intermediate pcsitions of .the shoulder plate are, for intermediate-sizes of tires.

Adjacent abutting ends of the/shoulder plate sections have respectively a stud 25 and a socket 26 disposed to receive the stud. A washer 21 and a nut 28 on the'stud together clamp the adjacent ends of shoulder plate sections.

To close the gap 29 that is left between abutting ends when the shoulder plate sections are moved apart longitudinally, an offset closure plate 30 is provided. This closure plate is welded to the end of each shoulder plate section bearing the stud, as suggested at 3l,fand the stud 25 -may be welded in a socket on the back face of the plate 30, the latter welding being suggested at 60. g

In the form shown in Fig. 6, an annular tread plate 32' is mounted on feet 33. The tread plate The tread plate 32 may be made sectional.

It is to be understood that when it is desired to receive a tire of larger or smaller diameter,

tread plate sections l2 or 32 may be removed and similar sections having larger or smaller radii may be substituted therefor.

Shoulder plate sections 35 may be fastened together at their ends by the means described above and shown on Sheet 1 of the drawings.

The sections 35 have steam spaces 36. It is believed clear without illustration that suitable connections may be made between the steam spaces Bland 3B anda steam source (not shown).

The form of vulcaniZer shown in Fig. 6 is bisected transversely and the halves are hinged together :at 31', and fastening'means 38 are ,pro- 'yidedfcrvthe segments.

the

Flanges 39 on the shoulder plate sections 35 carry rightand left-hand tapped lugs ts.

into the tapped lugs, for movement of the sections 35 in opposite directions. A crank handle 52 is afforded to operate the shaft 4|.

Lugs 43 are mounted on the outer circumferface 48. At opposite edges of said face, the plate ll has 'flat shoulders 39 disposed at right angles to the edges of the plate and parallel with the outer circumference .59 of theplate. Shoulder plate section 5! is slidable laterally upon the flat shoulders 49. Fillers 52 of varying sizes are placed between the shoulder plate and the curved face 58, to accommodate tires of different thicknesses.

In the form shown in Fig. 1Q, tread plate 53 v has a plurality of grooves longitudinally of its inner circumference 5% as illustrated at 55. Shoulder plate section has a boss 51 that fits into any selected one of the grooves. A corresponding construction is had at opposite edges of the face 54. v I

When one of the grooves 55 is exposed, as

shown in Fig. 10, it will merely form a decorative ridge on the tire.

. In the use of my full-circle, sectional shoulder plate, the sections are slidable on the inclined surface of the tread plate. As the sections are moved to different planes up and down the incline, the radius of, the full circle varies. That is, when the shoulder plates T5 are at the upper portions of the inclines at the edges of the tread plate [2, as shown in Figure 3,the radius of the circle of shoulder plate sections is shorter than the radius of the circle of these sections when they are moved down the incline, as shown in IEigure 2. To compensatercr this variation 'and to avoid having gaps around the'circle, closureplates 38 are employed to overlap adjacent ends of the sections.

The studs 25, nuts 28, washers "21 and sockets 25 provide means for holding together the adjacent ends of the sections in a 'pluralitybf "adjusted positions.

The'h'andles Z3 afford adjusting means for permitting the springs 24 to move the shoulder sections outward. The slot 'td'compensates for the rise and fall of the shoulder section relative to the tread plate.

In the form shown in Fig. 7, the shaft t! looks the shoulder sections 35 in adjusted :positions and also provides means formoving the sections to different desired positions toward and away from each other. Since .the sections rise and fall because of the inclines on the tread plate 32,the shaft ll must follow these movements. Theelongated slot 44 permits lateral movement of the shaft, while'the key l6 prevents longitudinal movement of theshaft.

\ In the form shown in Figure 9, the spacers 52 I of varying sizes may be used to fill in gaps'between the shoulder plate 5| and the curved surface 43 of the tread plate.

In the formshown'in 'Fig, 10, modified means of locking shoulder platesections 5t i i-adjusted A, rightand left-hand threaded shaft M is screwed positions on the inclines of a tread plate 53 are shown. The means of locking abutting ends of the shoulder sections, as shown on Sheet 1, may be employed in connection with the construction of Fig. 10. It is believed clear from the drawings that the bosses 51 of the shoulder sections. 56 will fit in any of the grooves 55. When combin- 1 ing the end-locking means for shoulder sections,

shown in Sheet 1, and themeans shown in Fig.

10 for locking the shoulder sections in the tread plate, the two "lockingmeans cooperate to maintain the shoulder sections in adjusted'positions relative to the tread plate. v While I have illustrated and described what I now regard as the preferred embodiment of my invention, the construction is, of course, sub- I lect to modifications without departing from the spirit of my invention. I therefore, do not wish to restrict myself to the particular form of construction illustrated and-described, but desire to avail myself of all modifications which may fall within the scope of the appended claims.
